Estrogen receptor signaling in the human breast epithelium

Breast cancer is the most diagnosed malignancy in women worldwide, making effective prevention strategies crucial. Hormonal contraceptives, consisting of a synthetic progesterone receptor agonist alone or in combination with an estrogen, are used by millio ...

An automatic multi-tissue human fetal brain segmentation benchmark using the Fetal Tissue Annotation Dataset

Meritxell Bach Cuadra, Hamza Kebiri

It is critical to quantitatively analyse the developing human fetal brain in order to fully understand neurodevelopment in both normal fetuses and those with congenital disorders. To facilitate this analysis, automatic multi-tissue fetal brain segmentation ...

Epigenetic remodelling of enhancers in response to estrogen deprivation and re-stimulation

Ludovica Vanzan

Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investigated geno ...

A high resolution LC-MS targeted method for the concomitant analysis of 11 contraceptive progestins and 4 steroids

Alexandre Béguin, Cathrin Brisken, Marc Moniatte, Jonathan Paz Montoya, Marie Shamseddin, Csaba Ferenc László, Fabio De Martino

In the context of hormonal contraception and hormone replacement therapy (HRT), many women are exposed to exogenous hormones. Current use of hormonal contraception with combined ethinyl estradiol and different progestins bestows a breast cancer relative ri ...

Progestins used for hormonal contraception in Switzerland: study of their effects on the breast epithelium

Marie Shamseddin

Breast cancer is the most commonly diagnosed cancer and the most common cause of cancer death among women. Hormones have been shown to have a key role in breast development and carcinogenesis. Repeated activation of progesterone receptor (PR) signaling as ...

Structural Brain Network Reorganization and Social Cognition Related to Adverse Perinatal Condition from Infancy to Early Adolescence

Jean-Philippe Thiran, Elda Fischi Gomez

Adverse conditions during fetal life have been associated to both structural and functional changes in neurodevelopment from the neonatal period to adolescence. In this study, connectomics was used to assess the evolution of brain networks from infancy to ...

Lactoferrin during lactation reduces lipopolysaccharide-induced brain injury

Yohan Van de Looij

Lactoferrin (Lf), component of maternal milk, has antioxidant, anti-inflammatory and antimicrobial properties. Neuroprotective effects of Lf on the immature brain have been recently shown in rodent models of intrauterine growth restriction and cerebral hyp ...

Unaltered cocaine self-administration in the prenatal LPS rat model of schizophrenia

Erika Myrna Borcel Novoa

Although cocaine abuse is up to three times more frequent among schizophrenic patients, it remains unclear why this should be the case and whether sex influences this relationship. Using a maternal immune activation model of schizophrenia, we tested whethe ...

The effects of stress during early postnatal periods on behavior and hippocampal neuroplasticity markers in adult male mice

Maria del Carmen Sandi Perez, Olivia Zanoletti, Jocelin Grosse, Michael van der Kooij

Infancy is a critical period for brain development. Emerging evidence indicates that stress experienced during that period can have long-term programming effects on the brain and behavior. However, whether different time periods represent different vulnera ...

Evaluation and Comparison of Current Fetal Ultrasound Image Segmentation Methods for Biometric Measurements: A Grand Challenge

Meritxell Bach Cuadra, Xavier Bresson, Anca-Ramona Ciurte

This paper presents the evaluation results of the methods submitted to Challenge US: Biometric Measurements from Fetal Ultrasound Images, a segmentation challenge held at the IEEE International Symposium on Biomedical Imaging 2012. The challenge was set to ...

Definition and quantification of acute inflammatory white matter injury in the immature brain by MRI/MRS at high magnetic field

Nicolas Kunz, Rolf Gruetter

Background: Intrauterine growth restriction (IUGR) is a major risk factor for both perinatal and long-term morbidity. Bovine lactoferrin (bLf) is a major milk glycoprotein considered as a pleiotropic functional nutrient. The impact of maternal supplementat ...

Effects of clofibric acid alone and in combination with 17 beta-estradiol on mRNA abundance in primary hepatocytes isolated from rainbow trout

Kristin Schirmer

Clofibric acid (CA) is the active substance of lipid lowering drugs. It is resistant to degradation, polar in nature, and has been found ubiquitously in the aquatic environment. Though CA is classified as a peroxisomal proliferator in rodents and is consid ...

Does Cancer Start in the Womb? Altered Mammary Gland Development and Predisposition to Breast Cancer due to in Utero Exposure to Endocrine Disruptors

Cathrin Brisken

We are now witnessing a resurgence of theories of development and carcinogenesis in which the environment is again being accepted as a major player in phenotype determination. Perturbations in the fetal environment predispose an individual to disease that ...

Impact of environmental estrogens on fish considering the diversity of estrogen signaling

Research on endocrine disruption in fish has been dominated by studies on estrogen-active compounds which act as mimics of the natural estrogen, 17 beta-estradiol (E2), and generally exert their biological actions by binding to and activation of estrogen r ...

Monitoring proliferative activities of hormone-like odorants in human breast cancer cells by gene transcription profiling and electrical impedance spectroscopy

Horst Vogel, Samuel Terrettaz, Horst Pick, Olivia Baud, Cathrin Brisken

The human estrogen receptor alpha (ER!) mediates the proliferative action of hormones in breast cancer cells by regulating the expression of target genes to control cellular functions. Current methodologies do not permit a real-time assessment of these pro ...

General developmental health in the VPA-rat model of autism

Henry Markram, Kamila Markram, Mônica Regina Favre, Georges Khazen

Autism is a neurodevelopmental condition diagnosed by impaired social interaction, abnormal communication and, stereotyped behaviors. While post-mortem and imaging studies have provided good insights into the neurobiological symptomology of autism, animal ...

Cyclin D1 Enhances the Response to Estrogen and Progesterone by Regulating Progesterone Receptor Expression

Cathrin Brisken

Estrogen and progesterone are the defining hormones of normal female development, and both play critical roles in breast carcinogenesis. Cyclin D1 is a breast cancer oncogene whose amplification is linked to poor prognosis in estrogen and progesterone rece ...
